Scientists searching for the origins of COVID-19 have zeroed in on a short list of animals that possibly helped spread it to people, an effort they hope could allow them to trace the outbreak back to its source.Researchers analyzed genetic material gathered from the Chinese market where the first outbreak was detected and found that the most likely animals were racoon dogs, civet cats and bamboo rats. The scientists suspect infected animals were first brought to the Wuhan market in late November 2019, which then triggered the pandemic.Michael Worobey, one of the new study’s authors, said they found which sub-populations of animals might have transmitted the coronavirus to humans. That may help researchers pinpoint where the virus commonly circulates in animals, known as its natural reservoir.“For example, with the racoon dogs, we can show that the racoon dogs that were (at the market) … were from a sub-species that circulates …
